I bought a Maserator pump at West Marine, it had the best price at the time, yet is a 1-1/2" female pipe thread, and I had to make an adapter for the RV outlet. Once that was done, I was able to dump the black tank into a port-a-potty that was located near where my RV was parked.
I used 1" clear plastic tubing to make the connection from RV to port-a-potty, then used grey water to rinse out the hose before putting it away.
1" tubing is about 2-3 times the opening of a normal garden hose. A garden hose can take a really long time, and has lots of back pressure. If you do go the garden hose route, try to keep it at 25' and with 3/4" hose if possible. It would be a expensive hose, and the tubing that I bought was around $1.10 per foot (40 feet was around $50) at Home Depot.
So all in all, the total cost to me was about $170 for the pump, $20 for fittings, and $50 for tubing. I was able to save monthly $35 dump fee for 4 years.
